Download or read book Two dimensional Compressible Flow in Centrifugal Compressors with Straight Blades written by John D. Stanitz and published by . This book was released on 1949 with total page 712 pages. Available in PDF, EPUB and Kindle. Book excerpt: Six numerical examples are presented for steady, two-dimensional, compressible, nonviscous flow in centrifugal compressors with straight blades. A seventh example is presented for incompressible flow. The solutions also applye to radial-flow turbines with rotation and flow direction reversed. The effects of variations in following parameters were investigated: (1) flow rate, (2) impeller-tip speed, (3) variation of passage height with radius, and (4) number of blades. The numerical results are presented in plots of the streamlines, constant Mach number lines, and constant pressure-ratio lines. Correlation equations are developed whereby the flow conditions in any impeller with straight blades can be determined for all operating conditions.

This book was released on 1951 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two numerical examples are presented for two-dimensional, compressible, nonviscous flow in centrifugal compressors with backward-curved, logarithmic-spiral blades. The two examples are for different blade angles and are compared with a third example for straight, radial blades. The numerical results are presented in tables of the stream-function distribution and in plots of the streamlines, constant Mach number lines, and constant-pressure-ratio lines. In addition, a simplified analysis for logarithmic-spiral blades is presented that can be used to determine flow conditions within the impeller except near the imperller tip and impeller inlet.

Download or read book Two dimensional Compressible Flow in Conical Mixed flow Compressors written by John D. Stanitz and published by . This book was released on 1948 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: A general method of analysis is developed for the two-dimensional, steady, compressible flow through mixed-flow compressors and turbines in which the center line of the passage generates a right circular cone about the axis of the machine. The two-dimensional, radial-flow compressor is a special case in which the cone angle is equal to 180 degrees. The variables taken into account are: (1) impeller tip Mach number, (2) flow rate, (3) blade shape, (4) passage height, (5) number of blades, and (6) cone angle. Relaxation methods are used to solve the resulting nonlinear differential equation for the stream function.

Download or read book Approximate design method for high solidity blade elements in compressors and turbines written by John Stanitz and published by Рипол Классик. This book was released on 1951 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: An approximate blade-element design method is developed for compressible or incompressible nonviscous flow in high-solidity stators or rotors of axial-, radial-, or mixed-flow compressors, turbines, or two-dimensinal cascades. The method is based upon channel-type flow between blade elements on a specified surface of revolution that lies between the hub and shroud (casing) and is concentric with the axis of the compressor turbine. The blade elements is designed for prescribed velocities along the blade-element profile as a function of distance along meridonal lines on the surface of revolution. Two numerical examples are presented: (1) the design of a blade-element profile for a plane two-dimensional cascade in compressible flow with the prescribed velocities along the profiles; and (2) the design of a blade element for the impeller of a mixed-flow centrifugal compressor.

This book was released on 1949 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: A procedure is presented for design of two-dimensional channels for compressible nonviscous flow. The method requires boundary conditions consisting of the shape of one channel surface and the velocity distribution on that surface. The process consists of the step-by-step computation of an arbitrary number of streamlines within the channel.
Download or read book Effect of Mach Number on the Flow and Application of Compressibility Corrections in a Two dimensional Subsonic transonic Compressor Cascade Having Varied Porous wall Suction at the Blade Tips written by William B. Briggs and published by . This book was released on 1952 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: A 65-(12)10 compressor blade cascade was evaluated at design geometry for Mach numbers from 0.12 to 0.89 with the boundary layer controlled through upstream slots and porous walls. The suction control was specified by a two-dimensionality criterion. The data show the effect of Mach number on turning angle, blade wake, blade profile pressure distribution, and static-pressure rise. The influence of suction on these parameters and secondary losses is illustrated. A system for correlating the experimental static-pressure rise with with the theoretical is presented. Prandtl-Glauert and Karman-Tsien compressibilty correction predictions are compared with the data. A new method utilizing the vector-mean velocity and the contraction coefficient is presented.

Download or read book A Rapid Approximate Method for Determining Velocity Distribution of Impeller Blades of Centrifugal Compressors written by John D. Stanitz and published by . This book was released on 1951 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: A rapid approximate method of analysis was developed for both compressible and incompressible, nonviscous flow through radial- or mixed-flow centrifugal compressors with arbitrary hub and shroud contours and with arbitrary blade shape. The method of analysis is used to dermine approximately the velocities everywhere along the blade surfaces, but no information concerning the variation in velocity across the passage between blades is given. In eight numerical examples for two-dimensional flow, covering a fairly wide range of flow rate, impeller-tip speed, number of blades, and blade curvature, the velocity distribution along the blade surfaces was obtained by the approximate method of analysis and compared with the velocities obtained by relaxation methods.
